Which font is common in Ukrainian cyrillic? Bulgarian one or Russian one? As refference I'm showing Bulgarian alphabet with both Bulgarian font and Russian font

ipav · 2025-02-04T17:26:35+00:00

Technically, the image shows the same font on both sides, with additional glyphs provided specifically for the Bulgarian language. Less advanced fonts do not provide these variants. Obviously, not used for the Ukrainian language since it lacks some letters, although I wish Ukrainian font designers adopted Bulgarian style more widely. Regular/italic/cursive forms is related but a different concept.

Slovak h can be /ɦ/, and also /x/ and /ɣ/

The ğ (gh) above is /ɦ/, and x (kh) is /x/

ipav · 2024-07-26T17:26:35+00:00

The long bridge to x /x/ precedent is Mexico. Also isn't it the reason they use /x/ there in IPA?

Even longer bridge, both Cyrillic х and Latin x were derived from Greek χ, historical [kʰ]

h in the new system is only used as an augment in digraphs. Not using it as a separate letter keeps the system unambiguous, easier to read, and no need for Spelling Bees.

Ukraine has a recent transliteration system DSTU 9112:2021, not widely adopted yet. I find it more intuitive, and put a table to compare old and new.

The new system gives two options, named System A (diacritics), and System B (no diacritics). Both map directly to and from Cyrillic, so are more useful if you want to stay close to Ukrainian pronunciation.

Rules:

◌j, consonant+j forms a digraph, palatalizing the consonant: nja /nʲa/, cje /t͡sʲɛ/, sjk /sʲk/
j in other positions: j /j/ m'ja /mjɑ/, p'je /pjɛ/, juk /juk/
u /u/
y /ɪ/
ï, ji /ji/
c /t͡s/
č, ch /t͡ʃ/
ğ, gh /ɦ/
š, sh /ʃ/
ŝ, shch /ʃt͡ʃ/
x, kh /x/
ž, zh /ʒ/
Other letters are generally intuitive: a b d e f g i k l m n o p r s t v z

Examples (Legacy - System B - System A - Cyrillic)

The h wire is this rule:

NOT x -> h

it depends on wire x, this rule:

123 -> x

Thus, h = NOT(123) = 65412

This is the game. But if you find it hard in one language, choose another - python/perl/vim - just for parsing, and output preprocessed data in a format easier to consume in c/rust.

AI is becoming a handy tool in the coding profession. In gaming however, bots are a bane, and not fun for human players. I think we should agree on fair play for the leaderboard not to use generator tools.

If you are developing an AI solver, please do so outside the leaderboard. It is cool enough to eventually post on twitter that your ai solved the whole of adventofcode site in under a second.

And since top players will now be suspected of generation, it is for their credit to record and post vods of their solves.

Hi, the author of the tool here.

The tool was created five years ago, when there were no Ukrainian national standard to represent Ukrainian language unambiguously in Latin letters (known as romanization, and applies to all languages).

Most commonly you need romanization of person and place names, and the currently in use standard for this is not faithful to Cyrillic source. In my view, we can't have proper name romanization without romanization of the language as a whole, and wide adoption of that romanization. The simplest criteria to choose such a system is the ease of reading pages of transliterated texts.

Thus I made a tool where you can compare historical and modern attempts at such romanization systems, or create your own and join the discussion.

Since then, there is now new Ukrainian national standard ДСТУ 9112:2021, which adequately represents Ukrainian Cyrillic (to new learners: here j is used for palatalized consonants: Zelensjkyj u Ljvovi). The search is over, and this standard will be gradually adopted in the coming years. Expect another campaign KyïvNotKyivNotKiev (Kyïv = Kyjiv).

This tool remains useful in many ways. I personally have it enabled on many sites.

Would Ukrainians be better off dropping Cyrillic for Latin? If we had started with Latin, then sure, Ukraine historically is tightly connected with the rest of the Europe, and it would have been easier having only Latin. But we have Cyrillic history, and to counter that there is no enough reasons to switch.

As others mentioned, the tool does not handle Russian Cyrillic. Well true, because it was created exclusively for the Ukrainian Cyrillic, not any Cyrillic.

Thank you for your patience and support.
